Abstract
A system and method for reading multiple items bearing electronic tags, such as radio frequency identification (RFID) tags, disposed in a read zone wherein a correlation scheme/system, separate (e.g. non-RF) from the electronic reader, is provided for verifying that all the items in the read zone have been successfully read. Typically, the user/operator is then notified whether or not all the items detected by the verification system have been successfully read by the electronic reader.
